Silicones are ________. Select one: A. flat sheets of silicon and hydrogen atoms B. flat sheets of silicon atoms C. chains of al
ternating silicon and oxygen atoms with attached organic groups D. three-dimensional covalent networks of silicon atoms E. three-dimensional covalent networks of SiO4 tetrahedra
Option C. chains of alternating silicon and oxygen atoms with attached organic groups
Explanation:
Silicones are polymers which comprises of repeating units of siloxanes i.e a chain of alternating silicon and oxygen atoms combined with an organic group which includes: carbon and hydrogen with other elements.
C. chains of alternating silicon and oxygen atoms with attached organic groups
Explanation:
It contains Silicone-Oxygen backbone as found in Silicone Dioxide (silica) but it also has organic groups attached to this backbone with Carbon-Silicone attachments. This whole arrangement of Silicone, Oxygen and Attached organic groups make up Silicones.
This is thermodynamics. When you increase the temperature of an object, the particles gain on kinethic energy ergo the move faster. When you decrease it, they slow down.
